Chen Shuhui looked at Chen Laowu again and asked Aunt Ma: "What injection did he get? How many injections did he get? When did he find himself deaf?"

"What acid, salicylic acid? I forgot. I got an injection!" Aunt Yang said regretfully.

This is something she doesn't want to remember for the rest of her life. She doesn't want to remember at all, but she really can't remember it.

At that time, they didn't have much money, they were only enough for injections.

"After the child came back, I found something was wrong. He disagreed with calling him. At first, I thought he was uncomfortable and didn't want to talk to anyone. Later, I found out that he was deaf." Aunt Ma said.

"Can he cure it?" Ma Qiuping asked hopefully.

If the fifth child is ready and her father is underground, will he close his eyes?

Chen Shuhui shook her head regretfully and listened to them. The child is deaf because he carries the deaf gene.

This is because children's own genetic defects, coupled with drugs, lead to death of cochlear hair cells or nerve damage.

This damage cannot be repaired.

This is a genetic disease. Ma Qiuping must have carried the deaf gene and passed it on to several children.

"These children will have their own ideas in the future. They should not take drugs such as gentamicin, neomycin, streptomycin, salicylic acid, uric acid, etc., otherwise they will also be deaf." Chen Shuhui said.

There were too many drugs. She didn't say much about them. Aunt Ma and Ma Qiuping were both shocked.

I'm too scared and don't know what to do.

Aunt Ma suddenly felt very lucky because her family was very poor. These children had been sick many times since childhood and had no money to get injections, otherwise they would become deaf

Fortunately, this deaf gene was passed on from women to men.

If the mother gives birth to a boy, the boy will carry the deaf gene. If he injects himself, he will become deaf. But if the child he gives birth to does not have the deaf gene, the gene defect will end here.

If the mother gave birth to a girl, the genetic defects will continue to spread and the child born to the girl will carry the deaf gene.

A terrible genetic defect.

Decades later, after the birth of newborns, genetic screening can be used to determine whether they carry deaf genes.

But now, doctors don't know what the gene is.

These words cannot be said to the mother and daughter at the same time.

Ma Qiuping has a problem, which means Aunt Ma has a problem too.

Yes, they all have to die from guilt.

"You two can't get injections. I will tell you one by one, you will remember it." Chen Shuhui said.

"What's wrong? What's wrong? Is there something wrong with my family?" Aunt Yang asked suddenly.

Chen Shuhui didn't explain, but she guessed it.

People don't know what genes are, but they have known "heredity" since ancient times.

"It's nothing, just for safety reasons." Chen Shuhui changed the topic: "Although Xiao Wu's ears cannot be cured, his vocal cords are fine. After special training, he can still speak like a normal person. If he can learn lip words again, his life will not be problematic."

"Can he still talk?" Aunt Ma and Ma Qiuping were shocked again.

Chen Shuhui really brought them too many surprises today.

In fact, Chen Shuhui did not say everything. Whether the deafness caused by injection can be recovered depends on the depth of the poisoning and the length of time.

Some people do not completely lose their hearing function. Some neurotrophic drugs can restore some of their functions.

However, Young Master Hua has been deaf for a long time and has not thoroughly examined her. She dare not say these things now, for fear that they will be disappointed.

However, when Aunt Ma and Ma Qiuping told Ma that they could only talk at the age of five.

Now they do not ask for anything else, they only ask him to live like a normal person in the future, encounter less discrimination, be able to get married, and support himself.

So they died peacefully.

As for Chen Laosan.

Ma Qiuping looked away with difficulty. She must have done something wrong in her previous life, and God would punish her like this.

"It's too late. Get some rest. You have to go up the mountain tomorrow." Aunt Yang wiped her tears and asked Chen Shuhui to go back and rest.

The cemetery in the mountain village is in the mountains, and it takes more than an hour to walk.
